Summary: Commons Logging is missing from shaded Flink Table library
Key: FLINK-9234
URL:
https://issues.apache.org/jira/browse/FLINK-9234 Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.4.2
Environment: jdk1.8.0_172
flink 1.4.2
Mac High Sierra
Reporter: Eron Wright
Attachments: repro.scala
The flink-table shaded library seems to be missing some classes from {{org.apache.commons.logging}} that are required by {{org.apache.commons.configuration}}. Ran into the problem while using the external catalog support, on Flink 1.4.2.
See attached a repro, which produces:
